Making LFO Settings
“LFO Curve” in the lower right of the screen shows a wave graphic that corresponds to the current settings.
Parameter Value Description
Waveform
(LFO Waveform)
SINE Sine wave
TRI Triangle wave
SAW Sawtooth wave
SQR Square wave
RND Random wave
TRP Trapezoidal wave
S&H Sample & Hold wave (one time per cycle, LFO value is changed)
CHAOS Chaos wave
Offset (LFO Offset)
-100, -50, 0,
+50, +100
Raises or lowers the LFO waveform relative to the central value. Positive (+)
settings will move the waveform so that modulation will occur from the central
value upward. Negative (-) settings will move the waveform so that modula-
tion will occur from the central value downward.
Key Sync
(LFO Key Sync Switch)
OFF, ON
This specifies whether the LFO cycle will be synchronized to begin when the
key is pressed (ON) or not (OFF).
Delay Time
(LFO Delay Time)
0–127
Delay Time (LFO Delay Time) specifies the time elapsed before the LFO effect
is applied (the effect continues) after the key is pressed (or released).
After referring to
“How to Apply the LFO”
(p. 123), change the setting
until the desired effect is achieved.
Rate (LFO Rate)
0–127, Note
Adjusts the modulation rate, or speed, of the LFO.
LFO Rate sets the beat length for the synchronized tempo when the tempo
that specifies the LFO cycle (Patch Tempo) is synchronized with the tempo set
in a external sequencer.
(Example)
For a tempo of 120 (120 quarter notes occur in 1 minute (60 seconds))
Setting
(half note) 1 second
(60 / 60 =1 (second))
(quarter note) 0.5 seconds
(60 / 120= 0.5 (seconds))
(eighth note) 0.25 seconds
(60 / 240= 0.25 (seconds))
This setting will be ignored if the Waveform parameter is set to “CHAOS.”
Fade Mode (LFO Fade Mode)
ON <<,
ON >>,
OFF <<,
OFF >>
Specifies how the LFO will be applied.
After referring to
“How to Apply the LFO”
(p. 123), change the setting
until the desired effect is achieved.
Fade Time (LFO Fade Time)
0–127
Specifies the time over which the LFO amplitude will reach the maximum
(minimum).
After referring to
“How to Apply the LFO”
(p. 123), change the setting
until the desired effect is achieved.
